Repro code sample for demo-ing hyper slowdown with large payloads of around 16 MB. There seems to be a 2x speedup when the client sends data in frames rather than a full payload.
Assuming that you have openssl installed, running the following command
./scripts/local_certs.sh
should result in the creation of
- repro-ca-cert.pem
- server-cert.pem
- server-key.pem
- server-ext.cnf
These files will be used by the client and the server
The key difference is between the using frames or not when using large buffers on the server side. The difference does not change dependent on the use of http or https.
